MySQL needs to support emoji emoticons version requires greater than 5.5.3, and the character set needs to be set to the UTF8MB4 character set.
What's the difference between utf8mb4 and UTF8? The original MySQL UTF8 a character up to 3 bytes, while UTF8MB4 expands to a character up to 4 bytes, so it can support more character sets.
Converts the MySQL encoding from UTF8 to UTF8MB4.

expressed using multiple bytes to express a symbol. For example, the common encoding method in Simplified Chinese is GB2312, which uses two bytes to represent a Chinese character, so it is theoretically possible to represent a maximum of 256x256=65536 symbols.The issue of Chinese coding needs to be discussed in this article, which is not covered by this note. It is only pointed out that although a symbol is represented in multiple bytes, the Chinese character coding of the GB class is irrelevan
